DISCUSSION.

The family planning research in Taiwan is one of the largest social science experiments ever carried out under controlled conditions, as of September 1, 1964. The author has no reason to doubt this claim; rather, the author like to recall to your minds one of the lessons from what was one of the first social science experiments ever carried out under controlled conditions. The expectation in the Taiwan research was that diffusion would take place, and the deliberate planning for its occurrence is one of the most intriguing aspects of the research design. Diffusion has been made an experimental variable of the first order. The author's own prediction is that the proliferation of social research in the developing countries will have an impact as profound as the introduction of Western technology. The author also recalls another pioneering series of experiments that took place at about the same time in a factory of the Western Electric Co., near Chicago, Illinois. Girls working at assembling various electrical components were observed over a period of years, and their average production rate was recorded.
